Patented Sept. 30,. 1947 UNITED STATE s 1 PATENT oFFlcE 2,423,085V lLocr Hors-rma -AND HAULING naar William M. Largeu, Roanoke, Va.application october c5, 194i,`serial No. 560,316 y This .inventionrelates to log hoisting Aand haul Y l ing carts, and has more particularreference to atwo-wheeled trailer type such as is adapted 'to b'ehitched to a tractor orother powering vehicle, fand the primaryobjective 'of the invention is to generally, specifically and otherwiseimprove uponvr known marketed and patented log wagons, this in a mannerto better serve 'the aims and requirements of manufacturers and usersalike.

The purpose of this .log 4cart er trailer fis to lift saw quicklybecomes dull'ed, and the `sawmill must be shut down for sharpening thesaw a number of times each shift. By carrying the log with only one end"scraping along the ground, it is pcs-v sible vto keep theA log almost'entirely'clean land the reefs'harpening period, twenty minutes, isf

eliminated entirely. except 'du-'ring the noon rest time,:f=an'd:"at theend of the shift. If the saw Iis not dulled -lcyfdirt, the whole sawingoperation is speeded up considerably, and several hours sawing time'saved duringeach shi-it. f

- One phase of apparent novelty has to do with the adoption and use of awell balanced, simple,

two-wheeled cart characterized by a horizontal frame, a perpendicularframe vattached to and rising vertically therefrom, andan upwardlyinclined, rearwardly projecting boom attached to said frames andprovided at its rear hoisting 'and hauling zend with 'a`cable-acommodation sheave.

Further novelty is predicated upon the wheelsupportedV axle, thisprovided with a motiontransmitting, fixedly mounted gear meshing with apower take-off gear on a suitably mountedshaft, appropriate operationalfacilities being provided between said axle and shaft, and said shaftcarrying abrake-equipped drum for cable winding and reeling purposes.

In carrying out the preferred embodiment of the invention; IV havelevolved and produced anaclequate vand expedient structural assemblagewhich is comparatively simple, substantially fool-proof,

sturdy 'and reliable, and otherwise constructed and -balancedto achievethe desired Vaims in `a practicable and reliab'lernanner.

Other features andfadvantages will becomemore readily apparent from thefollowing description andtheaccompanyng illustrative drawings.

'I'his boom issuitably inclined and has its forward end attached to the correspondingend of the frame and has its rear end provided with an adapter bracketI2 well over and beyond the rear end of the frame and carrying a pulleyor sheave I3. The frontal portion of the frame 8 is provided with atongue I4 and an appropriate hitchl I5 attachableY tothe tractorconnection shown j in I dotted lines in Figure 1. The rear axle vI6"(see Fig. 6) is journaled for rotation in bearings provided in the sidemem bers of the frame 8 and the projecting outer the cable so that thelog grabs can be set in the ends have traction-type, ground-engagingwheels I1 loosely mounted for rotation thereon. In

this connection, it will be observed that a ratchet pawl I9 (see Fig. 7)is pivotally mounted on 4 so that the main pulley drum cannot revolveand allow the cable to run out or olf of the drum. I-Ie disengages theclutch wheel from the gear wheel on the same axle so that the revolutionof the cleated wheels is not transmitted to the pulley drum. Or, inother words, the machine is allowed to run entirely free. The operatorthen proceeds to the place where he desires to pick up the logs, andbacks the tractor and log cart -to a point as closer as he can to thelog or logs he desires to haul to the sawmill set. The operator thenreleases the hand brake arrange- `ment so that the drum runs free, andpulls out log orv logs he proposes to haul to the sawmill.

`The operator then remounts and sees that the hand brake is not set. Hethen pulls the con- Ytrol cable so that the lugs of the pulley wlheelthe hub of the wheel so that when lthe machine* is pulled forward bythetractor, the axle is thus turned. This pawl and ratchet arrangementalso provides for the aforementioned back-up and differential actionpreviouslyset forth.4 While considering Figure 6, it willebevobserved'that a suitable gear 2llis xedlymountedon the axle, this beingthefpowertransmission' gearv which serves in a manner to be hereinafterset forth.

During the hauling otheiilogsirfrom thesite where cut to thesawmill`set; thewlog wagonis pulled by a tractor-.Knot shownlian'd its'`operation is as follows: 1 f

The tractor operator reache-sffoverthe of hisseat and sets the controltothe :brake 'leverf will become engaged in the gear wheel, thustransmitting all motion from the cleated wheels to the cable drum. HethenV puts the tractor in motion, and the weight of the logs on thecable and pulley causes a great deal of traction on the cleated wheels,which, as soon as they start, of course, cause the dr-um to revolve andthis causes the cable to be wound up on the drum. The operator drivesthe tractor and wagon forward far enough for the front end of thedragged logs to be Well olf of the ground. He then disengages the clutchwheel from the gearr by the control on the front end of the log wagon.At the same time, he sets the hand brake so that the pulley drum cannotVrevolve, and the logs now being securely held at one end well olf theground, the operator proceeds to the sawmill set, dragging thelogsbehind the log wagon, with only one end of the logs draggingon thegrounds,

It has been found that the weight of the logs Y transmitted through the.cable to the sheave Wheel, and from there through the boom and frame tothe cleated wheels provides simple traction so that. the drum alwaysrevolves when the controls are properly set, and the wagon is pulledforward, thereby winding up the cable and so dragging and lifting thelogs being hauled.

'Novelty is thought to reside in the horizontal and vertical frames 8and 9 suitably wheel supported andv theinclined boomV II, this extendingwell to the rear of the trailerand Wheels on` said .trailer to providethe requisite accommodation base and elevation for lifting` the log endsto the desired points fordragging purposes.

Additional novelty is predicated on the shaft, drum, gear and clutchassembly emphasized in the construction shown in Figure 4.
